Constructor.

dberr_t Row_sel_get_clust_rec_for_mysql::operator()	(	row_prebuilt_t *	prebuilt,
		dict_index_t *	sec_index,
		const rec_t *	rec,
		que_thr_t *	thr,
		const rec_t **	out_rec,
		ulint **	offsets,
		mem_heap_t **	offset_heap,
		const dtuple_t **	vrow,
		mtr_t *	mtr,
		lob::undo_vers_t *	lob_undo
	)

Retrieve the clustered index record corresponding to a record in a non-clustered index.

Does the necessary locking.

Parameters

[in]	prebuilt	prebuilt struct in the handle
[in]	sec_index	secondary index where rec resides
[in]	rec	record in a non-clustered index
[in]	thr	query thread
[out]	out_rec	clustered record or an old version of it, NULL if the old version did not exist in the read view, i.e., it was a fresh inserted version
[in,out]	offsets	in: offsets returned by rec_get_offsets(rec, sec_index); out: offsets returned by rec_get_offsets(out_rec, clust_index)
[in,out]	offset_heap	memory heap from which the offsets are allocated
[out]	vrow	virtual column to fill
[in]	mtr	mtr used to get access to the non-clustered record; the same mtr is used to access the clustered index
[in]	lob_undo	the LOB undo information.

Does the necessary locking.
